What is Devoicing?
Devoicing (DeV), also called Postvocalic Devoicing, is a phonological process typically lasting up to the age 4 years. In this process, voiced consonants at the end of words (e.g., /b/ in “web”) become voiceless (e.g., /p/ in “wep”).
Examples:
dog = dock
hide = height
move = moof
bridge = britch
web = wep
